Possibilities of using a photovoltaic system in a family home
Herník, Martin ; Linda, Jakub (referee) ; Toman, Filip (advisor)
This bachelor thesis deals with the design of a photovoltaic power plant that will meet the needs and conditions of a specific family house. The design includes photovoltaic options such as battery and non-battery system solutions. In this work, the selection of appropriate components was made, where the emphasis was on achieving optimum system performance and minimizing costs while maintaining given efficiency and reliability. Finally, the economic evaluation of the two solutions in terms of cost and paybacks is assessed. The final design is proposed in the light of the current energy price situation and the continuous forward movement of PV technology.

Determining the health status of the primary Li cell
Černík, Michal ; Vanýsek, Petr (referee) ; Bača, Petr (advisor)
This paper discusses the issue of determining the health and state of charge of cells and batteries. These parameters are an important component in all applications involving cells and batteries, in terms of their effectiveness and protection of personnel and the cells themselves. The method of electrochemical impedance spectroscopy, the method of relaxation time distribution and the design of an equivalent replacement circuit are explained and implemented in detail. LiSOCl2 type primary cells were used to implement these methods. The results demonstrated the functionality of the relaxation time distribution method and pointed out the shortcomings of the equivalent replacement circuit design method.

Controll Electronics for Effective Supplying of Equipment with Li-Ion Accu by Solar Cells
Horký, Luděk ; Dřínovský, Jiří (referee) ; Urbanec, Tomáš (advisor)
This Bachelor`s thesis deals with questions surrounding the collection and harnessing of solar radiation for use as electrical energy. The aim of this project was to build an effective system for charging Li-Ion batteries by means of solar cells. To this end, four different solar panels currently available were chosen for measuring and evaluation. The most suitable of these was chosen and an electronic control system devised for effectively supplying the Li-Ion batteries. It was necessarily to make solution for problems consequent upont this method of charging this type of battery and make practise realizitaion of this electrical scheme by SMT technology.

Study of fluorescence lifetime and spectral changes of nanoparticles in cell biology
Pelc, Pavel ; Janoušek, Oto (referee) ; Čmiel, Vratislav (advisor)
This work deals with the study of fluorescence lifetime and spectral changes of nanoparticles in cell biology. It describes the principle of fluorescence, fluorescence microscopy and laser confocal microscope Leica TCS SP8. The classic FLIM method, the Lambda Square mapping and the division of nanoparticles are introduced there. In the practical part, the created program for the evaluation of fluorescence lifetime and spectral changes is described. The program can show two-dimensional lambda maps, the fluorescence lifetime and spectral shift in the space area. In the final part of the thesis, an experiment with rhodamine nanoparticles is carried out and it is evaluated using the created program and then discussed.

Development and design of a modular battery box.
Rozinek, Josef ; Buday, Vladimír (referee) ; Porteš, Petr (advisor)
Tato práce se zabývá problematikou battery packů. V první části popisuje návrh battery packu z hlediska volby baterií, jejich tvaru, velikosti, typu a konfigurace zapojení. Dále uvádí vliv těchto charakteristik na výkonnost battery packu a jeho spolehlivost. Zabývá se problematikou termálního managementu battery packů a jeho vlivu na životní cyklus baterií. V druhé části se zabývá praktickým návrhem konceptu battery packu pro Lithium-polymerové baterie. Kalorimetricky je zde zjištěno množství produkovaného tepla při vybíjení, které je poté využito v CFD simulaci chlazení článku.

Localization of the caller in emergency medicine information system
Maleňák, Filip ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
Aim of this bachelor’s thesis is to analyze methods that are used for localization of the caller during emergency call to 155 and the importance of an accurate localization during the rescue operation. Describe other methods that can be used for localization of the caller and draft of the solution for use these methods to enhanced localization of the caller. Emergency line is presented by the module of emergency operation center in emergency medical service information system. Proposed solution for enhanced localization of the caller is given by the iPhone application iSOS. The application was designed on requirement of simplicity and maximum efficiency of caller localization in emergency situation.
